The Foreign Intelligence Surveillance Act (FISA) court system will not work if political parties are using it to fight each other, House Intelligence Committee Chairman Devin Nunes, R-Calif., insisted Monday, while denying claims in the Democratic response to his memo on FBI spying that the use of the FISA was allowed when it came to the Russian probe.

"The bottom line with the court is this, that we can't have a secret court operate like this in America, where they are going to take use it against political enemies," Nunes told Fox Business' "Mornings With Maria" host Maria Bartiromo. "It is not going to work if that is the case."

The Intelligence Committee released the Democratic rebuttal Saturday, two weeks after President Donald Trump allowed the Republican memo to be released. The posting came after a deal was reached requiring parts of the initial memo to be redacted because of national security concerns about methods and sources used to compile the document.

Nunes said Republicans actually wanted the Democratic memo to be released because it "proves everything" in the GOP memo to be true.

"We talked specifically about FISA abuse, and they are actually saying that it is O.K. for one party to essentially get dirt and use it to spy on another party," Nunes said. "That just never is going to be okay in America."

Nunes said he believes the use of the FISA court to get a warrant against campaign aide Carter Page was because people "at the very top" decided to use the "political dirt" contained in British spy Christopher Steele's salacious dossier on Trump to fight back because the New York real estate mogul won the presidency.

"They just could never believe that President Trump won the election," he said. "That is what this is about, in my opinion, and because, look, we looked for collusion. I said from the beginning, I will be the first one to come out to say if there is any evidence of collusion whatsoever. I will come out, and I will come on your show, and say to American people 'look, we for sure know that the campaign was colluding with Russians this is how we know it.'"

However, the mainstream media is ignoring that "we found collusion between the Democrats and the Russians," Nunes said.

The lawmaker has started phase two of his investigation into the issue, sending a letter with 10 questions to people in both the Trump and in former President Barack Obama's administration, asking for information about the Steele dossier and how it was used.

Nunes also said Democrats were responsible for numerous leaks of their memo before it was finally released.

"We know for sure there were several leaks," he said. "We think there's about 100 leaks from their side that leaked out to the media. That's roughly our count now."
